Sauerkraut and pickles are canned foods that have a long history. Sauerkraut is a cabbage dish pickled in vinegar, salt, and other seasonings. Pickles in the United States are most commonly cucumbers, but there are also pickled green beans, carrots, okra, onions, beets,and other vegetables. In Korea, kimchee, like sauerkraut, is made of cabbage and other vegetables, but kimchee is pickled and fermented in large casks, and tends to be quite spicy.
Fresh cucumbers, cabbages, and carrots are part of a summer diet. In summers past, humans ate foods from the fields and gardens, and also prepared some of the excess for storage. Such stored foods saved lives during harsh winters or during droughts.
In the winters, cold weather dominated many parts of the world. The land might be icy and white with snow. People went to their sheds and cellars, and retrieved the pickles, sauerkraut and other foods canned, salted, or sugared during the summers. These foods kept folks happy and well-nourished until winter faded and spring sunshine and rains crept back in, when edible dandelion leaves, mushrooms, wild berries, and other delicacies started to return, when farmers tilled their fields, and families planted their own favorites in back-yard gardens.
